Definitions

  • the present invention relates generally to methods and devices used in intravascular therapeutic and diagnostic procedures. More particularly, the present invention relates to methods and apparatus for providing therapeutic and/or diagnostic devices to a desired vascular site through a dilation balloon catheter, while allowing the dilatation balloon catheter to be withdrawn from the desired area.
  • Intravascular therapeutic techniques such as angioplasty procedures, have been developed as alternatives to bypass surgery for treating vascular diseases or other conditions that occlude or reduce the lumen size of portions of a patient's vascular system.
  • a balloon catheter is typically inserted intravascularly into a patient through a relatively small puncture, which may be located proximate the groin, and navigated by a treating physician to the occluded vascular site.
  • a balloon catheter typically includes a balloon or dilating member at the distal end which is placed adjacent the vascular occlusion. Intravascular inflation of the dilating member by sufficient pressures, on the order of 5 to 12 atmospheres or so, causes the balloon to displace the occluding matter. It is known that a number of sequential balloon dilatations may be required to properly revascularize the occluded lumen and restore substantially normal blood flow therethrough. Because the effectiveness of any one balloon dilatation may not be known, it is desirable to view the vascular site after selected balloon dilations to monitor the progress and to determine if any adjustments should be made to the procedure.
  • One known method for viewing the vascular site is to inject a radiopaque die into the patient's vasculature. X-rays or the like may then be used to view the revascularized portion of the vessel.
  • a disadvantage of this approach is that extended exposure to X- rays can be harmful to both the patient and the treating personnel.
  • IVUS Intra-Vascular Ultra-Sonic
  • the IVUS device can be advanced down the guide wire lumen of a balloon dilatation catheter until the IVUS device is adjacent the dilatation balloon. After a selected balloon dilatation, the IVUS device may provide an image of the revascularized portion of the vessel.
  • a limitation of this approach is that the dilatation balloon often distorts the ultra-sonic image of the vessel, and thus the usefulness of the images provided by the IVUS device are negated.
  • the present invention overcomes many of the limitations of the prior art by providing a method and apparatus for introducing therapeutic and/or diagnostic devices through a balloon dilatation catheter and to an occluded vessel, while allowing the balloon dilatation catheter to be withdrawn from the desired area.
  • This may enable, for example an Intra-Vascular Ultra-Sonic (IVUS) device, to produce non-distorted images of a revascularized portion of a vessel.
  • IVUS Intra-Vascular Ultra-Sonic
  • a longitudinally extendable guide member is provided in a balloon dilatation catheter. Positioned within the longitudinally extendable guide member is preferably a therapeutic and/or diagnostic device, such as an IVUS device.
  • a therapeutic and/or diagnostic device such as an IVUS device.
  • the balloon is positioned adjacent an occluded site and inflated to dilate the occluding matter. Thereafter, and to view the revascularized portion of the vessel, the IVUS device may be advanced down the extendable guide member until the IVUS device is adjacent the desired site.
  • the balloon dilatation catheter may be pulled proximally relative to the extendable guide member.
  • the dilatation balloon is effectively moved proximally away from the IVUS device, while the IVUS device remains adjacent the revascularized portion of the vessel. That is, and in a preferred embodiment, the extendable guide wire lumen member and the IVUS device remain substantially stationary relative to the revascularized portion of the vessel.
  • the IVUS device may then be used to provide an image of the revascularized portion of the vessel. It is noted that the extendable guide member may provide protection to the IVUS device while the balloon dilatation catheter is withdrawn proximally therefrom.
  • the balloon catheter may easily be repositioned across the site by simply re-advancing the balloon catheter over the extendable guide member. This configuration provides an efficient means for dilating a vessel with a dilation balloon, and imaging the vessel between selected dilatations.
  • the balloon dilatation catheter includes an inflation tube with an inflation lumen extending therethrough. Attached to a distal end portion of the inflation tube is an inflatable balloon. The interior of the inflatable balloon is in fluid communication with the inflation lumen of the inflation tube. In this configuration, the inflatable balloon can be expanded by applying pressure to the inflation lumen.
  • an elongated guide member preferably coextends interiorly within at least a portion of the inflation lumen of the balloon catheter, and is in a slidable relation therewith. The elongated guide member is also adapted to slidably receive an elongated device such as an IVUS device.
  • a sealing means is provided in the balloon catheter.
  • the sealing means slidably receives the guide member and provides a seal between the inflation lumen and the exterior of the intravascular catheter. The seal thus allows the guide member to be longitudinally slidable relative to the balloon catheter while enabling the dilatation balloon to be inflated when desired.
  • the sealing means comprises a seal between the inflation tube and the guide member.
  • the guide member may be slidably positioned relative to the dilatation balloon.
  • an IVUS device that is positioned within the guide member may be slidably positioned relative to the dilatation balloon, and in particular, selectively positioned distally of the dilatation balloon.
  • a first illustrative method includes the steps of: providing a catheter that has a movable guide member therein and a balloon located on the distal end thereof, wherein the catheter is positioned within the body such that the balloon is located adjacent the selected portion of the vessel; providing an elongated device that has an imaging device located near the distal end thereof, wherein the elongated device is positioned within the guide member; moving the catheter proximally of the selected portion of the vessel while leaving the movable guide member substantially stationary relative to the selected portion of the vessel; positioning the elongated device adjacent the selected portion of the vessel; and imaging the selected portion of the vessel with the imaging device.
  • a standard balloon catheter is combined with a lumen extension device.
  • the lumen extension device is a separate device that is used in conjunction with a catheter that has a guide wire lumen therein.
  • the lumen extension device allows a user to selectively extend the guide wire lumen of a conventional catheter.
  • the lumen extension device includes an elongated guide member for slidably receiving an elongated device, such as an IVUS device.
  • the guide member is adapted to be slidably disposed within the guide wire lumen of the standard catheter.
  • Attached to the proximal end of the guide member is a housing.
  • the housing preferably engages the proximal end of the catheter, and has a control mechanism for controlling the relative longitudinal position of the guide member relative to the catheter.
  • the catheter has a manifold on the proximal end thereof, and the housing is attached to the manifold.
  • another illustrative method including the steps of: providing a catheter that has a guide wire lumen extending longitudinally therethrough, and a balloon located on the distal end thereof, wherein the catheter is inserted into the body such that the balloon is positioned adjacent to the selected portion of the vessel; providing a lumen extension device comprising an elongated tube, wherein the lumen extension device is slidably positioned within the guide wire lumen of the catheter; providing an elongated device that has an imaging device located near the distal end thereof, wherein the elongated device is positioned within the elongated tube of the lumen extension device; moving the catheter proximally of the selected portion of the vessel while leaving the guide member of the lumen extension device substantially stationary relative to the selected portion of the vessel; positioning the elongated device adjacent the selected portion of the vessel; and imaging the selected portion of the vessel with the imaging device.
